KODAK ATTACHMENT FOR TAKING MOTION-PICTURES.

Application filed March 1.

T 0 all whom it may concern:

Be it known that I, JAMES E. WELGH, a citizen of the United States, residing at Shreveport, in the parish of Caddo and State of Louisiana, have invented certain new and useful Improvements in Kodak Attachments for Taking Motion-Pictures, of which the following is a specification.

My invention relates to attachments for kodaks and more particularly to devices for operating kodaks, and the object is to provide a simple mechanism for operating kodaks to secure a series or a number of impressions, which mechanism will operate to feed a film intermittently and automatically operate the shutter releaser, and also to provide means in combination with the shutter releaser to screen the film in order to space the impressions on the film. The film moving mechanism must be timed with the shutter releaser so that the proper amount of film will be fed to receive the impression 1i ivhen the mechanism stops the moving of the Other objects and-advantages will be fully explained in the following description and the invention will be more particularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of this application.

Figure 1 is a side elevation of sufficient arts of a kodak to illustrate the principal ttachments. Fig. 2 is a detail view of the riving gear for the operator attachment. Fig. 3 is an edge view of the same gearing with a section of the casing for the operator and a portion of a kodak. Fig. 4 is a rear elevation of the kodak with the casing removed to show the screen attached to the kodak. Fig. 5 is a perspective View of the screen. Fig. 6 is a bottom plan view of the bracket which holds the plunger of the shutter releaser.

Similar characters of reference are used parts throughout the several views.

The device herein set forth includes means for actuating the shutter releaser, means for feeding the film intermittently, and for screening the film. The kodak will not be described as it forms no part of the invention.

The plunger 1 of the shutter releaser is held in position (to be actuated) by a bracket 17 which is attached to the casing 3 Specification of Letters Patent.

b a shank 18 and bolts 19. The bracket 17 0 amps the holder 20 of the shutter releaser therein and holds the same by friction. The caslng 3 is mounted on the side of the kodak by means of clamps 4. A shaft 5 is connected with the shaft of the kodak film roll 2. A gear wheel 9 is rigid with shaft 5. A shaft 7 is journaled in the casing 3 and a mutilated gear wheel 6 is rigid with shaft 7. A gear wheel 10 is also rigid with shaft 7. A gear Wheel 11 is mounted on a shaft 12 which is journaled in the casing 3. The wheel 11 carries aneccentric pin 14 for actuating a pawl 13 which is pivotally mounted on the shaft 7. The shaft 7 may be turned by a crank 8. A turning of the crank 8 will drive the mutilated gear wheel 6 will drive the wheel 9 intermittently and the film roll 2 will thus be driven intermittently and will stand still at predetermined periods for the purpose of receiving impressions. Turning the crank 8 will also drive the gear wheel 10 and this wheel drives wheel 11 which will actuate the pin 14 and thus the pawl 13 will be actuated to operate the plunger 1. The operation of the plunger will be at regular intervals and the film will move at regular intervals and stop at regular intervals. The moving and stopping of the film must be so timed that it will stop at the moment the pawl 13 actuates the the blan on the gear wheel 6 reaches the gear wheel 9.

When the machine is in operation, a screen 15 is necessary to prevent the impressions from running into each other. The screen 15 is a thin piece of sheet metal with an opening 16 cut therein for exposing a portion of the film to receive the impression. A screen will be necessary in the finder 21 to proportion the image according to the dimensions of that part of the film which is exposed through the opening 16 in the sheet metal screen 15.

What I claim, is,

1. A kodak operator comprising a shutter releaser and a plunger therefor, a casing attached to a kodak casing, gearing in said casing operatively connected with the film roll of the kodak for moving the film intermittently, means on said casing for holding the plunger of the shutter releaser in operative position, and a pawl actuated by said gearing for operating said plunger.

2. A kodak operator comprising a shutter gear wheel 6 and this plunger 1. The film will stop when i releaser and a plunger therefor, gearing operatively connected with the film roll of the kodak includinga mutilated gear for driving the film roll intermittently, a pawl actuated by said gearing, and means for holding the plun er of the shutter releaser in th path oft e awl. 1 Y

3. A koda operator comprising a shutter releaser and a plunger therefor, gearing operatively connected to the film roll of the kodak including a mutilated gear wheel for operating the film; roll intermittently, a pawl actuated by said gearing, means for holding the plunger of the shutter releaser in the path of the pawl, and a screen for exposing a predetermined portion of the film 1 on each movement of the film.

4. A kodak operator comprising a shutter releaser and a plunger therefor, gearing operatively connected with the film roll of the kodak including a mutilated ear wheel for operating the film roll intermittently, a casing for said gearing attached to the kodak,

a pawl actuated by said gearing and projecting from said casing, and a bracket attached to said casing for holding the plunger of the shutter releaser in the path of the pawl.

5. A kodak operator comprising, a shutter releaser and a plunger therefor, gearing operatively connected with the film roll of the kodakincluding a mutilated gear Wheel for moving the film roll intermittently, a pawl actuated by said gearing, means for holding eratively connected with the film roll of the kodak for moving the film intermittently at regular intervals, means ,for holding the plunger of the shutter releaser' in operative position, means actuated by said gearing for reciprocating said plunger, and screening devices for exposing predetermined portions of said film on each movement of the film.

In testimony whereof, I set my hand in the presence of two witnesses, this 24th day of February, 1915.
